This invention relatesto a wrench set or combination and it particularlyaims to provide a structure having all of the necessary sockets orheads, for use in connection with dual wheels of Ford or other trucks,and for trailer wheels.

The invention resides in the novel combination of parts and detailshereinafter described with relation to accompanying drawingsillustrating an operative embodiment.

In said drawings:

Figure 1 is a view in elevation of the wrench set or assembly;

Figure 2 is a vertical section taken on the plane of line 2-2 of Figure1;

Figure 3 is a view in substantially central vertical section through theset or assembly;

Figured is a horizontal section taken substantially on the line t i ofFigure 3;

Figure 5 is a detail section taken on the line 5-5 of Figure 3;

Figure 6 is a detail section taken on the line i5 of Figure 3;

Figure 7 is an end elevation of the main tubular socket member, and

Figure 8 is a detail side elevation of the cup nut and collar nutconnected together.

Referring specifically to the drawings wherein like reference charactersdesignate like or similar parts, the invention employs an elongatedtubular main socket member it whose walls are concenas in a pawl andratchet, to turn the socket member in either direction, is pivoted at Itto a bolt spanning the plates Id. In order to hold the pawl it in eitherposition, that is with either end l'l engaged with the teeth, a detentl9 abuts the same on opposite sides of center, such detent beingslidably mounted in a tube Ell fastened to the handle and urgedoutwardly to the desired degree of frictional contact with the pawl O byan expansive coil spring 2! housed within tube Rotatably mounted withinthe main socket member it is an auxiliary socket member 22, the samebeing removable and reversible end to end, if desired. Such auxiliarysocket member has bearing flanges 23 contacting the inner wall of themain socket member Hi. At one end, auxiliary socket member 22 has awrench head 2i and at its opposite end it has a wrench head 25. The

head 2 is provided with a square or other socket 255 in the free endthereof, aligned with the socket [2. Head 25 also has a suitable socket227 in the free end thereof. Each of the heads 2d and 25 has an opening28 and 29 therethrough, selectively adapted to register with openings 3%in the wall of the main socket member it. A rod may be passed throughthe aligned openings 28 or it and openings 30 so that the socket membersiii and; 22 will rotate as a unit through operation of the handle, andin either direction, ac-

cording to the direction of rotation of the hande and position or" thepawl l6 With respect to the teeth l3.

It will be realized that the wrench may be used with any of the socketsl2, 2% and 27 engaged with a nut or other part and that the socketmember 22 may be reversed end to end so that either socket 27 or 26 willbe exteriorly thereof.

The invention is particularly useful as in connection With dual wheelsas referred to where a collar nut 31 and a cup nut32 are removed fromthe wheel and applied thereto as a unit, the same being removed andapplied when the hexagonal or octagonal portion of the nut 3| is engagedin the socket 52, with nut 32 outermost. After such unitary nuts havebeen removed, and it is desired to separate them, they may be applied inthe sockets l2 and 26 as shown in the drawings. In

such position, the handle may be turned and the A rod or the likeapplied in the opening 29 may be turned relatively thereto, so as tothereby detach nut 32 from nut 3!.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention:

A tool of the class described comprising a tubular socket member adaptedfor turning having a socket portion in oneend thereof, a removable andreversible auxiliary socket member rotatable within the first mentionedsocket member having socket portions in each end adapted selectively toabut the first mentioned socket portion and to aline therewith, thesecond mentioned socket portions being dissimilar, said auxiliary socketmember having openings therethrough one adjacent each end, the firstmentioned socket member having openings therethrough for alinement witheither of the first mentioned openings, so that an element may beapplied to connect the socket members for unitary rotation, saidauxiliary socket member being of a length to extend beyond the firstmentioned socket portion at the end opposite the socket portion toexpose the adjacent opening thereof for engagement by a turning elementwhen the socket members are operated one relative to the other to detachthe unitary nuts.
